This patch adds support for global error reporting for FPGA
Management Engine (FME), it introduces sysfs interfaces to
report different error detected by the hardware, and allow
user to clear errors or inject error for testing purpose.

Partial Reconfiguration (PR) is the most important function for FME. It
allows reconfiguration for given Port/Accelerated Function Unit (AFU).
It creates platform devices for fpga-mgr, fpga-regions and fpga-bridges,
and invokes fpga-region's interface (fpga_region_program_fpga) for PR
operation once PR request received via ioctl. Below user space interface
is exposed by this sub feature.
Ioctl interface:
* DFL_FPGA_FME_PORT_PR
Do partial reconfiguration per information from userspace, including
target port(AFU), buffer size and address info. It returns error code
to userspace if failed. For detailed PR error information, user needs
to read fpga-mgr's status sysfs interface.
